Always worth bearing in mind that the Citizen disk drives used by MGT/SAMCo were made around 1989-1991 or thereabouts, they were discontinued very early in SAM’s life so are getting on for over 25 years old! The belts will be perishing quite a bit and becoming slack, unfortunately I’ve not been able to get reliable replacements for a few years – not found another that I was 100% happy with.
The only solution I currently offer is my replacement disk drive system based around a modern PC disk drive and a new controller board -> www.samcoupe.com/hardfdc.htm <http://www.samcoupe.com/hardfdc.htm> Also, if of interest to anybody here I do have a couple offers on some hardware goodies and a bundle of SAM Revival magazines on the go at the moment -> www.samcoupe.com/offers.htm <http://www.samcoupe.com/offers.htm> Colin ===== Quazar : Hardware, Software, Spares and Repairs for the SAM Coupé 1995-2016 - Celebrating 22 Years of developing for the SAM Coupé Website: www.samcoupe.com <http://www.samcoupe.com> From: owner-sam-us...@nvg.ntnu.no [mailto:owner-sam-us...@nvg.ntnu.no] On Behalf Of Thomas Seifert Sent: 23 May 2016 13:53 To: sam-users@nvg.ntnu.no Subject: Re: R: Floppy disk drive error if the disk drive is older - like 10 years or more - could be the belt drive needs replacing as this is the most common fault with older SAM Coupe disk drives - you can get these from Colin Pigot (drive belts and also disk drives) >> http://www.samcoupe.com/hardware.htm Simone Voltolini <simone.voltol...@tin.it <mailto:simone.voltol...@tin.it> > schrieb am 14:26 Montag, 23.Mai 2016: I usually clean all my drives heads before use it but the original Citizen drives have problems with the BELT.

No, that's an unfortunate omission from the manual. Drive belt has been mentioned, but it can also be something fishy with the power supply, e.g. not delivering enough voltage to the drive. In very rare cases it can also be the disk presence switch which is faulty. But before you start opening up too much - are you sure you are using the correct bay? On SAM Coupé drive 1 is in the left bay, while on SAM Elite drive 1 is in the right bay. Regards, -Frode
